Appropriately use -ENOIOCTLCMD and -ENOTTY when the ioctl is not
implemented by a driver.
(akpm: we're not allowed to return -ENOIOCTLCMD to userspace. This patch does
the right thing).

Make rtc-dev work well on 64-bit platforms with 32-bit userland. On those
platforms, users might try to read 32-bit integer value. This patch make
rtc-dev's read() work well for both "int" and "long" size. This tweak is came
from genrtc driver.

Add the dev interface to the RTC subsystem.
Each RTC will be available under /dev/rtcX . A symlink from /dev/rtc0 to
/dev/rtc cab be obtained with the following udev rule:
KERNEL=="rtc0", SYMLINK+="rtc"
